  Performing L Measurements from LDC DRDY Timing
  PDF, 66 Kb, Archivo publicado: nov 6, 2015
  TI’s LDC1000 and LDC1101 devices measure the resonant frequency of an LC tank to determine the inductance of a sensor. Some applications require higher measurement resolution than the LDC1000 or even LDC1101 can provide. With proper configuration of the LDC, an external time measurement device can be used for improved inductance measurement resolution.

  Measuring Rp of an L-C Sensor for Inductive Sensing
  PDF, 205 Kb, Archivo publicado: oct 1, 2015
  When designing an application using TI’s LDC series of inductive sensors, it is necessary to know the L-C sensor’s equivalent parallel resistance RP at the sensor’s resonant frequency. The RP value changes as the target is moved; the minimum RP occurs when the metal target is closest to the sensor. The maximum RP occurs when the target is at the farthest distance. Accordingly, both values should b
